11.4
The IPR registers contain the individual priority bits for
the peripheral interrupts. Due to the number of
peripheral interrupt sources, there are six Peripheral
Interrupt Priority registers (IPR1 through IPR6). Using
the priority bits requires that the Interrupt Priority
Enable (IPEN) bit (RCON<7>) be set.
